T0 ali'wko mit may concern: Be it known that I, HARRY EBERT, a citi-Zen'of the United States, residing at Frederick, in the county ofFrederick and the State of lilaryland, have invented anew and usefulImprovement in Power Plants, of which the followingis a specification. f

This invention relates to improvements 1n power plants, and moreparticularly to that class where the power of a. prime movernecessa-rily operating at high speed, is appl ed to slow movingmechanism without excessive friction-and other losses incurred intransmission. r v

It is often advantageous to employ high speed :as the initial source ofpower, as the prime mover in this case is smaller, lighter in weight andrelatively more efficient; butit is a well known fact that in gearingdown, or sacrificing speed to gain power through the use of gear'wheels,belts and pulleys, etc,

there arenecessarily great losses due to fries tion and in overcominginertia of the moving parts, which increases rapidly as the ratiohetweenthe speeds of the. driver and driven in increased.- f

The primary object of this invention 15 therefore to provide means thatwill reduce these losses and increase the efliciency of the transmissiondevice by producing; the maximum-final efiort with the minimumexpenditure ofpower.

lVith this and, other objects in view, the invention resides in theapplication of certain principles and forms of construction involvingthe principle of the lever, the applications of which are clearly setforth in the accompanying specification and draw ing, in which:

Figure 1 represents a side elevation of power plant shown drivencombustion engine.

Figure 2 represents a top plan view of my power plant showing the upperwater reservoir.

Figure 3 represents a rear elevation of my power plant, showing asection of the lower water reservoir.

Similar symbols of reference refer to similar parts throughout theseveral views. Referring to the drawings, the numeral 1 inclicates afoundation, or base, which may be constructed in any approved manner,containing a lower water reservoir, 2. At the rear end of the base 1,three uprights or standards, 3, 4, and 5, which may be cony by aninternal I pivotally mounted rightsare provided with journals, 3 1?, andj oflrespec'tively, located near their upper, ends, through which arotatable shaft, 6 passes.

' Two ratchet wheels, 7 and 8, are mounted v i on the shaft 6,spaced'apart, and located between the-upri-ghts,3 and 4:, and twosprocketwheels, 9 and shaft 6, being 4 and 5. The ratchet wheels 7 and8, and the sprocket wheels 9 and 10, are all keyed, or otherwise securedto the shaft 6'so as to rotate With it. I A stationary shaft, 11 passesthrough openings 3'? and 4 7, located 'near the upper ends of theuprights, 3 and 4, being firmly secured thereto in any a-nd'two levers,l2 and 1,3, the ends of which are provided with eyes through whichtheshaft'll passes .The'levers'12 and 13 are spaced apart,-and free to moveon th'e'shaft 11, which acts as afulcrunr. A pawl 12 is on. the lever12, so as to 10, are alsopmounted on the located bet-weenthe uprights,

a proved manner,

engage the ratchet. wheel 7,'b.eing held in engagement therewith by a.fiat spring, .12" as shown. The lev r 18 is similarlyprovided with .apivoted pawl 13 and spring 13 in" order to engage the ratchet wheel 8.in the same manner.

A second pair of levers, 1 land. 15,, are journaled on a stationaryshaft, 16, which passes between and is supported by the twofront'uprights, 17 and 18, near their upper ends, the shaft 16 acting asa fulcrum for the two levers. The front, or shortest arms of the twolevers, 14 and 15, are p-rovidedwith a roller, 19 and 20, respectively,mounted at their extreme ends, upon which the ends of the main levers,12 and 13 rest; Guides, or yokes, 14 and 15 servetokeep the ends'of themain levers, 12 and 13, always on-the rollers in order to prevent anylateral movement.

The longer arms of the levers, 14 and 15,

are each connected with a connecting rod, or pitman, 14c and 15respectively, and the other ends of the pitman are each pivotallyconnected or journaled to ac'separate wrist pin on 'fly-wheels, 2121, ofap-rime mover, 22, represented in the drawings as an internal combustionmechanism.

In the drawings,the device is illustrated engine which operates the Iteasers ac lifting water for any purpose, and to this end, endlesssprocket chains, and 9A, carrying buckets, 25-25, pass over the sprocketwheels, 9 and 10, and submerged sprocket wheels, 9 and 10, convey waterfrom the lower reservoir, 2 to the upper reservoir, 26. The buckets25-25, are pivotally connected or mounted on rods, 27-27, connecting thetwo sprocket chains, 23 and 2e, so as to remain in an upright positionand filled with water until tripped by a stationary rod, :28 afterpassing over the sprockets, 9 and 10, and the water discharged into theupper reservoir, 26. A. bucket is indicated, partly by dotted lines inFigure 1 as discharging into the upper reservoir.

While the device as illustrated shows a method of raising Water from onelevel to anotherth rough the medium of buckets, etc., operated bycertain speed reducing mechanism, a pulley or pulleys may be mounted onthe shaft 6 in place of the sprocket wheels, 9 and 10, and powerdelivered from such pulleys by a belt for any purpose. Or, the shaft, 6may be also the main'shaft of any piece of machinery, or coupled to anymachine.

In operation, the main levers, 12 and 13, are lifted by power appliedalternately to their extreme ends by the short, or effort arms of thesecondary levers, 14; and 15, fulcrumed on the shaft 16.

As the long or effort arms of the second ary levers, 1d and 15, areconnected to the connecting rods, 14 and 15", journaled to wrist pins onthe fly wheels, 2121, set 180 degrees apart, each revolution of theengine shaft alternately raises and lowers each of the main levers,'12and 13, fulc-rumed at their opposite ends on the shaft 11. As each ofthe main levers starts to fall, the pawls 12 and 13, engage the ratchetwheels, 7 and 8, rotatin the main shaft, 6, adapted to furnish the powerrequired, as. the drawings disclose,v by lifting water through themedium of buckets and sprocket chains. The power of theengine 22 isabsorbed in raising the main levers, 12 and 13, which power is afterwardput forth by the levers descending and moving the ratchet wheels, 7 and8, by

the pawls, 12 and 13. The rollers, 19 and i the drawings.

2. A power plant comprising a generator provided with a pair of crankssubstantially diametrically opposed, a pair of levers driven by saidcranks by intervening pitmen, the levers each having a long and a' shOrtarm, the long arm connected to the crank, and a second pair of leversoperable by said first levers, the second levers each having a long anda short arm, the long arm of the second levers gravitating against theshort arm of the first levers and means connected with said secondlevers for transmitting rotary motion to another member.
